Default [Q] Crossflashing on Snapdragon LTE models?

Are ROMs cross flashable on the Snapdragon LTE models?

I saw a ROM that can be flashed on a variety of the Snapdragon LTE models and I am wondering if this applies to all ROMs.

This is because I come from the Xperia Z where ROMs are cross flashable between the 3G and LTE models of the device, due to them being internally identical just with different frequency bands.

If this is not the case then I will need to specifically find the SM-G900F which is difficult since in Australia I believe it is the SM-G900i model that is sold...
